I recently moved into a house with a 40 gallon gas water heater. The discharge pipe on the pressure relief valve is piped to recirculate to what I believe is the cold water supply to the water heater. There is a small cylindrical copper looking device that looks like it says "regulator" at a 90 bend in the pipe that returns the discharge to the supply.
Why would this be plumbed this way?
Is this setup safe?
I've always seen discharge pipes that are open at the end, about 6" above the floor.
